You order two servings of pancakes and a fruit cup. The cost of the fruit cup is $1.50 you leave a 15% tip. Your total bill is $

soldier1979 [14.2K]

1. Your total cost if 11.50 dollars.
It says that you ordered pancakes and a fruit cup
Pancake costs = x
Fruit cup cost = 1.50 dollars
you leave a tip = 15%

The equation would be:
=> (1.50 + x) .15 = 11.50 dollars
=> x = 11.50 – 1.50 x .15
=> Now, let’s find the cost of the pancake
=> 11.50 - 1.50 fruit cake = 10
=> 10 x .15 tip = 8.5
Thus, the price of the pancake is 8.5

Graph the feasibility region represented by the given inequalities and find the maximum profit if P = 4x + 5y. x ≥ 5 y ≤ 10 2x -

Brilliant_brown [7]

First, graph the three inequalities: x ≥ 5 , y ≤ 10 , 2x - y ≤ 8

Next, look for the 3 intersections (vertices) of the lines: (5, 2) , (5, 10) , (9, 10)

Finally, input the vertex coordinates into P = 4x + 5y and look for the biggest #.

(5, 2): 4(5) + 5(2) = 20 + 10 = 30

(5, 10): 4(5) + 5(10) = 20 + 50 = 70

(9, 10): 4(9) + 5(10) = 36 + 50 = 86

Answer: maximum profit = 86

Let X be the time it takes for a person to choose a birthday gift, where X has an average value of 27 minutes. If the random var

Answer:

The parameters of this exponential distribution is $\lambda$ = $\frac{1}{27}$ .

Step-by-step explanation:

We are given that the random variable X is known to be exponentially distributed and let X be the time it takes for a person to choose a birthday gift, where X has an average value of 27 minutes.

So, X = time it takes for a person to choose a birthday gift

The probability distribution function of exponential distribution is given by;

$f(x) = \lambda e^{-\lambda x} , x >0$ where, $\lambda$ = parameter of distribution.

Now, the mean of exponential distribution is = $\frac{1}{\lambda}$ which is given to us as average value of 27 minutes that means $\lambda = \frac{1}{27}$ .
